To all whom it may concern.

Be it known that I, WOOTSON L. SANDER- son, a citizen of the UnitedStates, residing at Meridian, in the county of Lauderdale and State ofMississippi, have invented certain new and useful Improvements inArtificial Stone or Bricks; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The present invention relates to artificial stone and brick, and aims toprovide a plastic composition composed of novel mixture 1 oringredients, providing a product closely imitating sand stone, which isalmost if not practically water proof, and which will resist fire, waterand climatic conditions equal to or better than the natural stone. Incarrying out the invention, the following proportional formula is used:

od syru of any kind. 95 pounds Po%%llmd*1!e%ent.

The ingredients above given are mixed perfectly while in a state, andafter being oroug y mlxe yen and one-half gallons of clean water areadded and mixed thoroughly. After thoroughly mix1ng the ingredients withthe water, untll the dampness is equal and perfect throughout themixture, showing no spots that are drier or damper than others, toassure of equal distribution of water throughout the mixture, thematerial is left standing for a period of one hour, after which thematerial can be molded into bricks or blocks suitable for buildingpurposes, and in any size, shape or fashion, to meet the demands ofmodern architecture and circumstances.

The bricks or blocks are then cured. Thus, when the bricks or blockshave been taken out or emptied from the molds or forms, the blocks areplaced on pallets or other supports within a shed or other shady laceout of the sunshine for three da s. he blocks are then sprayed lightlywith clean water three times a day, morning, noon and night, for aperiod of ten da s. Then, the blocks are sprinkled lightly with waterfor a period of five days twice a day, noon and night. This makes atotal of fifteen days that the material, after being molded, must remainin the shed or under protection from the sunshine and weather,

be sprayed conveniently over the bricks, and

the bricks or blocks are similarly stacked out in the open while aging.

The combination of materials used makes a close imitation of sand stone,andwhen mlxed and molded into blocks or bricks, as stated above, thefirst setting that is done 'forms a shell on the exterior, and thematerial sets and hardens from the exterior to the center, one course orlayer of hardening following another from the outside 1n, just the sameas in the natural stone. During the treatment of the blocks with water,they must not be flooded with water, or else they will crack, and if thedirections are followed closely, the resultant product will closelyresemble the natural stone as drawn from natural resources.

The amount of material specified will make five cubic feet of solidstone or about one hundred solid brick of universal or standard size.When made by this process, at the age of from sixty to ninety days, thebrick are almost if not practically water proof, and will resist fire,water, and climatic conditions equal to or better than the naturalstone.

The color of the brick or stone is light pink, dark pink, brown orchocolate, overned by the sand used. If the sand is w ite, the brick orstone will be light pink. If the sand is light red, the brick .or stonewill be dark pink. If the sand is dark red or brown, the brick or stonewill be brown or chocolate, respectively. The color' is absolutelylasting, as it is a part of the stone or brick itself.

Having thus described the invention, what In testimony whereof I havesigned my is claimed as new is name to this specification in thepresence 10 Artificial stone including, in approxiof two subscribingwitnesses. mately the proportions stated, 5 cubic feet VVOOTSON L S KNDERSON 5 of sand, 32- pounds red oxid of iron, 2?;

pounds plaster Paris, 1;} pounds of ocher, 1i Witnesses: pounds of salt,10 ounces of sugar, and 95 C. L. HUGHES, pounds of cement. E. L. GAsToN.
